This invention relates to devices known as stoma receivers and also sometimes known'ascolostomy and ileostomy appliances, which are used to receive bowel evacuations through surgically formed outlets where normal evacuation is impossible.

It is an object of the invention to provide a stoma receiver which includes interchangeable apertured portions through which the stoma extends, one of the elements being a simple apertured element which holds the stoma in the easing of the receiver, and which is adapted to be utilizedwhen the wearer isnot active, and the other element being provided with means for restraining the stoma against undue protrusion through thewall of the abdomen when the wearer tion of the stoma but which is outwardly yieldable to permit free evacuation when necessary.

Another object of the invention is to provide a stoma receiver which is so constructed that it can be readily adjusted to suit individual cases wherein, for example, the stoma may be located adjacent either groin or more nearly in the center of the lower abdomen.

A further object of the invention is to provide a stoma receiver of simple construction and including a pair of frictionally yielding separable sections which can be readily opened or separated by means of a simple opening device which is carried by one of the sections.

The above and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same parts throughout the views, and, in which:

Figure 1 is an elevational view of the inner side of an embodiment of the invention showing alternate positions of the inner section in full and dotted lines;

Figure 2 is an elevation of the outer side of the receiver illustrating the manner of supporting the same and securing it to the body of the wearer;

Figure 3 is a section taken approximately on the line 3-3 of Figure 1;

Figure 5 is an edge view taken approximately on the line 5-5 of Figure 4;

Figure 8 is an enlarged fragmentary view taken approximately on the line 8-8 of Figure 2; and

Figure 9 is a vertical sectional view through a modified form of stoma receiver casing.

In Figures 1 through 3 there is shown a casing Ill made up of an outer section II and an inner section l2. The sections II and I2 comprise mainly spaced side walls. The edges of the side walls are defined by flanges l3 and [4 respectively which concentrically fit with a relatively tight yet separably frictional engagement. The outer section II has a pair of countersunk buttons l5 formed thereon and they are adapted to fit button holes It in a body encircling strap I! which is adapted to hold the receiver in position and keep it pressed against the skin of the wearer.

The inner casing section I2 is provided with a circular opening l8 which, as shown in Figures 1 and 3, is off center and placed fairly close to the Its wall is tapered as shown in Figure 3.

:Frictionally seated in and removable from the opening I8 is a stoma ring l9 shown in Figures 1 and 3. It has a central aperture 20 through which the stoma 2| shown in Figure 3 is adapted to extend. The ring H has a pair of lateral extensions 22 shown best in Figures 4 and 5. Lying between them is a stoma restrainer element 23 which is pivotally connected between the extensions 22 by means of a frictionally held removable pin 24, shown in Figure 4. The lower portion of the restrainer 23 is in the form of a pair of divergent arms 25 between which lies a projection 26 which is an integral part of and an extension from the ring [9.

The upper portion of the ring 19 is provided with a spring pressed pin 21 whose pressure can be adjusted by a set screw 28. The spring pressed pin 21 bears against the upper portion 23a of the stoma restrainer 23. Since the spring pressed pin 2! lies above the pivot pin 24 it will yieldably urge the lower or major part of the restrainer 23 toward the stoma 2| and prevent the latter from working outwardly through the opening in the abdominal wall indicated at 29. However, when evacuation takes place the restrainer 23 can swing outwardly to about the dotted line position of Figure 3 so that the waste matter will fall into the main body portion of the casing 50. The stoma cannot slip downwardly by reason of the lower projection 23 which lies between the arms arms 25 which are a part of the restrainer 23.

The stoma restrainer unit just described is l separate.

particularly adaptable for use when the wearer is moving around. When the wearer sleeps a simple apertured stoma ring 30, such as shown in Figures 6 and 7, can be used. While the stoma ring with the restrainer produces some slight resistance to evacuation it is not objectionable, but the simpler ring 30 may be more desirable when the'restrainer is not needed.

In Figure 8: portions of the?casing' isections'lI and I 2 are shown, and flanges l3 and M are illustrated. The flange 13 on the outer section II is provided with a pivotally supported lever 3| connected to the flange l3 by a pivot pin 32. The larger end of the lever 3| iswshownuprovided with a rounded cam surface "SIai WheIi the lever is moved in a counterclockwise direction, as it is viewed in Figure 8, the camisurface 3la will bear against the edge Ida of'th flange l4 and cause the sections 1 I and I2 to readily In Figure 9 there is shown aone piece receiver -casing*33 which is providedwith a'simpleapertured stoma ring E l. It should be understood that a stoma ringequippedwitha restrainer such as the-restrainer *23 above--described-"can -be substitutedfor the ring 34.
